Abstract:
The present invention relates to a copolymer of the formula where A, B, and D are independently of one another an aliphatic (cyclo)alkylene radical, R is a C1-C10 alkyl radical, and 3≦x≦10. The present invention also relates to a process for preparing the copolymer, to its use and also to a coating composition and a coating formulation containing the copolymer.
Abstract:
An adduct of at least one isocyanatoalkyltrimethoxysilane with at least one flame retardant reactive with the isocyanatoalkyltrimethoxysilane is used in compositions and for coating plexiglass.

Abstract:
A reactive composition contains A) an aqueous polyurethane-polyurea dispersion containing an uretdione group and having an internal emulsifier, the emulsifier having at least one ionogenic group which, in the case of an acidic ionogenic group, has a pKa in water of >8 at room temperature or, in the case of a basic ionogenic group, has a pKb of >8 at room temperature, B) at least one diamine and/or polyamine, wherein a ratio of a latent NCO group in the polyurethane-polyurea dispersion A) containing an uretdione group to the amine groups in component B) is from 4:1 to 1:1, and C) optionally, at least one member selected from the group consisting of an auxiliary, an adjuvant and a catalyst.
Abstract:
The invention relates to innovative, water-dispersible, hydrophilic polyisocyanates and polyisocyanate mixtures, to a process for preparing them, to compositions comprising the hydrophilic polyisocyanates of the invention, and to their use as a starting component in the production of polyurethane plastics, more particularly as crosslinkers for water-soluble or water-dispersible film-forming, adhesives or sealant binders or binder components having groups which are reactive towards isocyanate groups.
Abstract:
